. Referring to the drawings more in detail, the invention is shown as "applied to a support ing mechanismior a projection machine in eluding-base 10, pedestal 11 and pedestal lever 12. Projection head 13 is mounted upon ede's'tal lever 12 in any convenient manner as is wellknfown in the art. Pedestal lever 12 is extended rearwardly to, support "a jlampho'use (notshown) and is provided withfa downwardly extending Web 14 which supports the driving 'motor and lower film magazine as will be described. a

Pedemal 11 includes a casing 1 5 and a to" member 16 which is supported thereby.

plurality of rods 17 are extended through base and top 16 for clamping said elements in fixed relationship. Pedestal lever 12 is pivoted to the forward portion of top 16 by 5 pin 20 and adapted to be moved about said pin as an axis for adjusting the vertical angle of the line of projection.

The rear portion of web 14 is formed as an arc of a circle drawn about pin 20 as a center. This portion of the web is adj ustably clamped to top 16 by wedge blocks 21 which are seated in suitable apertures in said top and are provided with flattened surfaces bearing against the arcuate edge of web 14. The wedge blocks are secured in top 16 by bolts 22 which are passed through said wedge blocks and threaded into said top.

The lower portion of web 14 is provided with an L extension 25 supporting a self aligning thrust bearing 26 on which shaft 27 of motor 30 is mounted. The forward portion of web 14 is provided with a bracket 31 on which motor 30 is adj ustably mounted.

Shaft 27 extends upwardly into the projection head and constitutes the drive shaft for the projection mechanism (not shown). The

lower film magazine (not shown) is mounted in bearing 32 of web 14 and is driven from shaft 27 through a suitable gear train comprising gear 33, shafts 34 and 35 and gears The particular drive for the lower film magazine, however, forms no part of the present invention. The adjustable self aligning thrust bearing 26 permits shaft 27 to be suitably adjusted with respect to the projection apparatus and with respect to motor 30. Motor 30 may also be adjusted on bracket 31 to properly align the various elements.

For angularly adjusting pedestal lever 12 about pin 20 there is provided a threaded rod which passes through a pivoted collar 41 (Figs. 6 to 8) having ears 42 which are carried in suitable slots in yoke 43. Screws 44 (Fig. 8) carried in yoke 43, are inserted after the pivoted collar has been positioned and prevent the latter from being removed. Yoke 43 is secured to the underside of top 16 by any convenient means such as bolts 45' (Fig. 4). Fixed collars 46 are carried on rod 40 on opposite sides of pivoted collar 41 and may be rigidly secured to said rod by convenient means, such asset screws 47, there by preventing longitudinal movement of rod 40 with respect to said pivoted collar.

The lower portion of rod 40cis threaded into threaded collar 50 (Figs. 9 and 10) having ears 51 which are pivotally mounted in suitable bearings in straps 52. Said straps are clamped to 2. lug 53 carried on web 14 and may be secured thereto by bolt 54. Hand wheel 55 is secured to rod 40 and provides for manual operation thereof whereby threaded collar 50 may be moved longitudinally of rod 40 for causing the desired pivotal movement 65 of pedestal lever 12.

An arcuate brace 60 is secured to base 10 by bolts 61 and is provided with an upstanding flange 62 (Fig. 3) which slidably engages a groove in the lower portion of web 14. Said web may be clamped to flange 62 by set screws 63. Base 10 is provided with a circular hole 65 and with an elongated arcuate slot 66 which are adapted to receive stationary bolts secured in the floor of the projection room whereby the machine may be rigidly secured thereto. Slot 66 is curved about hole 65 as a center whereby the entire base may be adjusted about a vertical axis as desired.

Base 10 is provided with legs 7 0 extending outwardly therefrom and terminating in supporting sections 71 (Fig. 5) in which feet 81 are adjustably'secured. Said feet include a curved supporting surface and threaded rods 72 which are mounted in threaded sleeve 73. Sleeve 73 is provided with a bottom flange 7 4 and is inserted in a suitable bore in supporting section 71 and is secured therein by cap 75 and set screw76. Pin 7 7 is secured to feet 81 and extends into a suitable bore in said supporting section. Pin 77 is provided with a flattened surface 78 whichbears againstflange 74 of sleeve 73 and prevents rotational movement of foot 71. Shoulders 7 9 and 80 of pin 77 prevent the foot from being entirely withdrawn from leg 70. Nut 82 is formed on cap 75 and provides means for rotating said cap and sleeve 73. Rotation of sleeve 73 varies the longitudinal position of rod 72 with respect thereto and controls the adjustment of feet 81.

In the supporting mechanism above describedthe entire machine is clamped to the floor by thebolts extending through slots 65 and 66 in the base and may be angularly adjusted as desired. The base may be suitably 1 leveled with respect to the floor by adj ustin the elevation of feet 81. This is accomplishe by turning nuts 82 thereby causing feet 81 to slide vertically with respect to sections 71 of legs 70. The vertical adjustment of the pedestal lever is then obtained by loosening bolts 22 and clamping screws 63. Hand wheel 55 may then be turned for pivotally moving the pedestal lever about pin 20 as an axis. hen the lever has been properly positioned clamping screws 63 may be again tightened there by securely clamping the lower portion of web-14 against arcuate brace 60 and bolts 22 are tightened for forcing wedge blocks 21 into engagement with the upper portion of web 14. The pedestal lever is thus supported at three separated points, namely, pin 20, wedge blocks 21 and arcuate brace 60. The entire projection apparatus including the driving motor is secured to web 14 of the pedestal lever and is accordingly moved as a unit thereby preventing the movement of the lever from disturbing the adjustment of the moving parts. The entire device is mounted in a particularly rigid manner by reason of the widely separated feet, as well as the means for clamping the base to the floor of the proestal, a base therefor, a pedestal lever carrying a utility and pivotally supported on said pedestal to tilt in a vertical plane, means for clamping said lever to said pedestal and guiding means secured to said base and cooperating with said lever to prevent lateral movement of said lever.
